Format

format1+Format Defined as `format(Format) :- format(Format, []).' format2+Format, +Arguments Format is an atom, list of ASCII values, or a Prolog string. Arguments provides the arguments required by the format specification. If only one argument is required and this is not a list of ASCII values the argument need not be put in a list. Otherwise the arguments are put in a list.

Special sequences start with the tilde (), followed by an optional numeric argument, followed by a character describing the action to be undertaken. A numeric argument is either a sequence of digits, representing a positive decimal number, a sequence `character, representing the ASCII value of the character (only useful for  t) or a asterisk (), in when the numeric argument is taken from the next argument of the argument list, which should be a positive integer. Actions are:

write_term2. This o

2. This option is SWI-Prolog specific.

Example:

Will output

format3+Stream, +Format, +Arguments As format2, but write the output on the given Stream. sformat3-String, +Format, +Arguments Equivalent to format2, but ``writes'' the result on String instead of the current output stream. Example:

sformat2-String, +Format Equivalent to `sformat(String, Format, []).'
